Composite decking is durable and can stand any test of mother nature. However, even the best composite decking materials will eventually be scratched. With increased use, the composite deck will slowly wear out. So, how to repair composite decking?

Of course, you don’t have to worry too much. When your composite deck is worn, we can use some composite decking scratch repair techniques.

Why are there scratches?

After installation, your composite deck looks very beautiful, and you like to spend time outdoors with friends and family. But over time, you begin to notice that your deck has small scratches in some areas.

These scratches are likely to be located in areas with high traffic, such as sidewalks leading to internal access points. The following are some of the most common reasons why composite deck boards are scratched over time:

Shoes, Boots, high heels, and even some formal shoes will wear and scratch your composite deck. You will notice these scratches more in areas such as sidewalks.

Children and pets. Toys, dog nails, and a range of activities with children and pets can cause scratches.

Outdoor furniture is usually heavy. This is a good thing because it ensures that your furniture remains in place. This also means that when your furniture moves, there is a greater possibility of scratches.

In some places, the winter weather is very bad. Rain, snow, sleet, and ice will damage your decking and its completion. The winter wind of moving large furniture will also produce scratches.

Repair skills of scratch on composite deck

Your composite decking material will never need to be sealed or painted because it is very durable and can withstand frequent abuse. However, annoying scratches can damage a great outdoor space. Here are some methods that can be used to repair scratches on composite decks:

Although your composite decking does not need to come in for regular maintenance with painting, it is a way to repair scratches and wear and tear. It can make the scratches on the surface of the deck disappear. However, this is not recommended, and if you use paint to repair the deck, it means that you will need to maintain and paint the deck on a regular basis in the future. Some brands do not offer a warranty on composite decking that has been painted.

Fill nicks and scratches with epoxy-based filler and a putty knife. When taking this route, please ensure that the product you use is approved by your decorative material manufacturer. Some kits provide everything you need for such repairs.

Try a hot compress. To do this, you will use a hot-air gun approximately 8 inches to 12 inches from scratch. At the same time, you will use a wire brush to scrape the decking in the same direction as this scratch. This is achieved by mixing scratch and non-scratch areas together.

Replace the scratch plate with a new one. This provides a perfect look. But it can be difficult to find exactly the same replacement plate years after your deck installation. Avoid this problem by purchasing additional composite materials during the first shopping. Some extra circuit composite boards can really help. If there are holes or burns in the decking, you can use the same method.

Consider consulting the manufacturer or retailer for your scratched decking. Composite materials are very strong and elastic, but problems may occur in some cases. Your composite decking manufacturer may recommend a repair method suitable. In many cases, they can also provide cleaning, maintenance, and maintenance skills.

Prevention of wear and tear of composite decking


If you are not careful, trying to repair the scratch of composite decking with very small wear or scratch may do more harm than good. This is especially true if you use heating methods. For composite decking, seasonal changes may help eliminate your scratches or make them less obvious over time. As your deck ages, scratches may better blend with the natural fading of any external material.

Even if you don’t have real handyman skills, scratch repair of composite decking is possible. After fixing your deck properly, you can take some measures to avoid scratches in the future. Here are several ways to prevent scratches and maintain the deck:

Use woven carpets designed for spaces with high traffic. Weaving carpets will help prevent shoes from damaging the flow of people. Outdoor coffee tables and other heavy objects can also be placed on the carpet to reduce long-term scratches.

Place the mat under the furniture on the deck. This prevents chairs, sofas, combination cabinets, and tables from scratching your deck when they slide slightly during use.

Put the furniture away when you’re not in use. This is especially important in winter because you may not use the terrace for months.

Use a broom instead of a shovel to remove leaves, snow, or other debris. Shovels and other hard tools will soon scratch your deck.

The composite decking materials are strong and durable enough to withstand dozens of harsh, snowy winters and hot summers. When scratches do occur, they are also relatively easy to repair. This makes composites an excellent choice for any outdoor space.
